Measles and Mumps The data show the number of cases of measles and mumps for a recent 5 -year period. Measles Cases 40 137 64 56 203 Mumps Cases 1701 650 2037 2578 375 The correlation coefficient for the data is =r−0.885 and =α0.05 . Should regression analysis be done? The regression analysis should not be done
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
